Trigonometry Functions
Functions of angles
side opposite / hypotenuse = sine side adjacent / side opposite = cotangent
side adjacent / hypotenuse = cosine hypotenuse / side adjacent = secant
side opposite / side adjacent = tangent hypotenuse / side opposite = cosecant
Finding the length of sides in right angle triangles when an angle and side are known
Length of side opposite = hypotenuse x sine
hypotenuse / cosecant
side adjacent x tangent
side adjacent / cotangent
Length of side adjacent =  hypotenuse x cosine
hypotenuse / secant
side opposite x cotangent
side opposite / tangent
Length of hypotenuse =  side opposite x cosecant
side opposite / sine
side adjacent x secant
side adjacent / cosine
